Restore pump status in Nightscout device status uploads

[bjorkert]

The next-dev rewrite of LoopDataManager dropped the code that attached device status to the dosing decisions Nightscout uploads. As a result devicestatus is missing its entire pump object — clock, reservoir, model, and so on — which downstream tools (Nightscout, LoopFollow) rely on. On current dev these fields were populated in update(for:).

NightscoutServiceKit's StoredDosingDecision.pumpStatus returns nil unless pumpManagerStatus is set, so with these fields unset the whole pump block is omitted from every upload.

This restores the same fields dev set, on the decisions NightscoutService actually uploads:

• updateRemoteRecommendation (routine): pumpManagerStatus, pumpStatusHighlight, cgmManagerStatus, lastReservoirValue
• manual bolus decisions: pumpManagerStatus, cgmManagerStatus (lastReservoirValue was already set)

DeliveryDelegate gains pumpManagerStatus, pumpStatusHighlight, and cgmManagerStatus; DeviceDataManager already provides all three.

Moving this to LoopKit#2460, since LoopKit/Loop is now the next-dev source.
